The Samsung E900, introduced in 2006, is a high-end mobile phone and is derived from Samsung's D500-D600-D800 series of slide phones. It is of a slide-up design and has touch-sensitive keys, similar to the LG Chocolate (KG800). It was one of the most popular phones at the time but was discontinued late 2007 when buyers then turned their attention to the Samsung D900i, followed by the Samsung U600, which was the slimmest phone by Samsung with a thickness of 1.09 cm (0.43 in) until the E840 was released.
This phone was the first phone released by Samsung with the new Black UI & White & White UI. This user interface was created to be more convenient and quickly learnable.
